HYDRAULIC APPARATUS FOR THE MANUFACTURE OF WINDOW-GLASS.

. SPECIFICATION forming part of Letters Patent NO. 713,758, datedNovember 18, 1902.

Application filed May 26, 1902.

To all whom it 'ntay concern:

Be it known that I, FRANCOIS G1 UANNOTTE, a subject of the King ofBelgium, and a resident of Oharleroi, Belgium, have invented an ImprovedHydraulic Apparatus for the Man 11- facture of VVindow-Glass, of whichthe following is a specification.

. This invention relates to an improved bydraulic apparatus formanufacturing window glass in a mechanical manner.

The annexed drawings, to which reference will be made in the followingspecification, illustrate a form of fconstruction of my improvedhydraulic apparatus by way of an example.

Figure 1 is a front elevation, partly in section; Fig. 2, a verticalcross-section; Fig. 3, an elevation showing the opposite end to that ofFig. 1; and Fig. 4 a side elevation thereof, corresponding to Fi 3.

The apparatus comprises two inverted vertical hydraulic cylinders I,mounted upon a convenient elevated supporting-frame H L at such a heightabove the ground as to afford easy working and ready passage beneath theapparatus. The piston-rods J of said cylinders are connected together ata certain distance by a cylindrical traverse K, from which is suspendeda fiat bar M by means of eyepieces, as shown in Figs. 1 and 2. The saidbar is faced with asbestos-board and carries at each end a screw 0,having elongated or high pitch. A second bar M is also faced withasbestos and suspended from the cylindrical traverse and provided withcorresponding holes for the reception of the screws 0 of the bar M. Inthe space comprised between the two bars M and M is a strip P, of glass,of a specified width and thickness and of a length limited by the screws0. This strip is slightly curved at its upper portion, and when pressedbetween the asbestos-boards by means of the flat bars M M and wingednuts engaged upon the aforementioned screws it can readily expand orcontract and at the same time support the sheet of glass which it has todevelop. The rods J of the hydraulic pistons are guided near their lowerends in guides V, connected with brackets fixed to standards or columnsU for the purpose of insuring perfect rectilinear motion to said rods.

serial No. 109,015. (No model.)

A trough or receiver A of refractory material, having an elongatedrectangular form, is charged with a suliicient quantity of molten glassB for the production of several sheets of glass. This trough is carriedupon a carriage (J, furnished with insulating material D between thebody thereof, and is introduced into a reheatingfurnace for the purposeof imparting to the glass the required temperature for forming thesheets. When the said trough is removed from the furnace, the carriage Ois received upon a truck E and is then run under the hydraulic apparatusand placed exactly in the axial line of the cylinders I. The truck E isprovided with two hinged gage-plates F, with angular upper ends, andarranged to be moved by means of levers G. When said angular gage-platesare standing upright, as shown in full lines at Fig. 2, they leavebetween their adjacent edges a narrow opening close to the upper end ofthe trough A, which opening serves for the passage of the glass P, so asto fuse it onto the molten glass in the trough and withdraw it from thelatter. By this arrangement the required temperature of the glass can bereadily maintained, While the trough is prevented from cooling tooquickly and cracking, and facility is afforded to the operators toapproach the apparatus.

The dotted lines F show one of the hinged gage-plates turned sidewise inits inoperative position.

\Vhen the trough has been properly placed beneath the hydrauliccylinders, the operator brings down on each side of the slot formedbetween the gage-plates two pipes R for the delivery of fresh airsupplied by a fan through longitudinal slots S of the tubes. A hydraulicthree-way cock, operated by a lever T, supplies Water under pressurefrom a pipe W in connection with any suitable source. The water can bedelivered above and beneath the pistons in the hydraulic cylinders,saidpistons being capable of being stopped at any point of their stroke. Xis the discharge-pipe for the Water. The operator opens the three-waycock by means of its lever T, so as to lower the starting blade or stripP into the trough and bring it near the molten glass, Where it becomesthen heated. After the blade has acquired sufficient heat it is loweredinto the molten glass and soon begins to form body therewith. Atthismoment the operator opens the air-valve and also starts the'hydraulicpistons to move upward. The molten glass adhering to the strip P forms asheet which cools as it issues from the trough, and in thus solidifyingit can be gradually lifted to a height according to any particularlength of sheet or glass. By more or less accelerating the upwardmovement the sheet of glass will be more or less thick. So soon as thesheet of glass has attained the required length the operator cuts itclose to the gage-plates F by means of an iron blade, Wire, or the likeand then raises the air-pipe, as indicated by the dotted lines, (seeFig. 2,) whenthe air may be shut ofi. Thereupon the trough is withdrawnand reintroduced into the furnace, if necessary, and the suspended sheetof glass Q is then received in a frame. Said frame is mounted on truck Aand is made entirely of in the clips.

wood, fitted at the upper end with two springclips D, designed to firmlyhold the sheet of glass between asbestos linings or pads and theuprights B. At the lower end of these latter are provided holes for thereception of wooden pegs or screws E for carrying the glass if thelatter is not sufficiently retained The operator while standing on aplatform 0', provided on the frame, takes 01f the winged nuts of theclamping-bar M and disengages the latter from the sheet Q. Themanufactured sheet is then taken to a room for the purpose of cuttingoff the strip P, which may serve again for a fresh operation.

WVhat I claim, and desire to secure by Letters Patent of the UnitedStates, is

1. In an apparatus for the manufacture of window-glass in sheets, thecombination with hydraulic lifting-cylinders mounted upon an elevatedframework, of a traverse connected to the piston-rods thereof, aclamping-bar suspended from said traverse and faced with asbestos andconnected with a similar asbestos-faced clamping-bar, a glass stripcurved at its upper part and clamped between said suspendedclamping-bars and a trough holding molten glass, to and from which thestrip may be moved.

2. In an apparatus for making sheet-glass, the combination withhydraulic cylinders mounted upon an elevated frame, -of a traverseconnected to the piston-rods thereof, clamping-bars suspended from saidtraverse, a glass strip clamped between said bars and curved at itsupper part, a trough charged with molten glass, a carriage carryingsaidtrough, a truck supporting said carriage, two plates hinged to the truckand forming a slot over the trough, and two removable air-tubes at thesides of the slot formed by the said plates.

3. In an apparatus for making windowglass, the combination with twohydraulic cylinders mounted upon an elevated framework, a traverseconnected to the piston-rods thereof, a bar suspended from said traverseand faced with asbestos and connected with a similar bar also faced withasbestos, a glass bait-strip and screws for clamping said bars thereon,of a wooden frame mounted on a truck, spring-clips secured to saidframe, to grip the finished sheet of glass, and adjustable pegs at thelower part of said frame for supporting the glass.

4:. In an apparatus for making sheet-glass, the combination with atrough holding molten glass, of a vertically-movable bait-strip clampedbetween bars and adapted to be moved to and from the trough to draw asheet therefrom, hinged plates forming a slotted cover over the trough,and air-pipes above the plates to deliver a cooling-blast against bothsides of the sheet as it issues from the trough.

In testimony whereof I have hereunto set my hand in presence of twowitnesses.

FRANCOIS GIUANNOTTE.
